Hi everyone,

I have a serious problem. Lately I've changed lots of computer parts: motherboard, processor, RAM and graphic card. They are all brand new (my specs are below). However, after 15 minutes, sometimes half an hour of intensive gaming (or even Windows-based work, like copying large files) I'm getting this STOP: 0x0000007F error.
I entered "My Computer", "Manage", "Event Viewer", "System". There is no log tagged "System Error", but the STOP error is still showing up.

I made some screenshots for you to analyse them, maybe they can tell you something about the nature of my problem- is it hardware or software related?


This is first error:




This is a different one, it popped up just today:




This is what I have:
CPU: Pentium 4 LGA755 3,0 GHz; 800MHz fsb; 1MB cache (I bought it used, but it's working well)
CPU cooling: Ninja Scythe Plus ans Arctic Silver 5 termal paste
Motherboard: Gigabyte GA-965P-S3 (brand new)
RAM: Goodram 667MHz DDR2 2x512MB CL5 dual channel (paired to work in dual channel, brand new)
Graphic card: Galaxy 7300GT 256MB, DDR3 Premium with Zalman cooling (brand new)
Power Supply: Antec 450W (brand new)
HDD: IDE 40 GB Seagate and SATA WD 200GB
soundcard: some Realtek mobo integrated one
DVD Recorder: LG multisystem


I have tested my RAM with this testRAM utility and it showed 10 errors within a 30-minute test. This is how a log-file from this operation looks like:

What does these results tell you?


Now here you can sneak a peek at how my BIOS looks like and if there's anything wrong with it. Basically I didn't change anything apart from S.M.A.R.T. HDD option, so I think everything should have [Auto] or default values:

Please help me, is there anything I can do? I'm really sick of this annoying error

I though the problem is RAM-related so I tried to change some timings, but I couldn't find how to do it from the BIOS level


EDIT: Oh, I forgot: I would have attached some minidump files, but after enabling this option, believe it or not, there are no files in the Windows/Minidump folder, there's even no such folder (I can see all the system and hidden stuff though), but the crashes are still there. I'm perplexed.

Have you checked the Ram manufacturer's operating voltage against the delivered voltage from the power supply? A similar problem intermittently occurred when my system was backing up to external drives. It turned out to be a power supply heating problem that lowered voltage output to RAM. Motherboard manufacturers often provide freeware that will monitor board voltages with adjustable alarm setpoints and reporting.

ok, i've installed the motherboard monitoring utility and that's how the voltages section looks like:



well it says OK next to the voltages, but if anything looks suspicious, I'll change that. what do you think?

Tried to post a detailled response, but have been getting a "you are not logged in" - if it takes more than 30 seconds. I'll rewrite offline and paste the response when I get time. Looks like there's a timeout on this site.

Ok. What motherboard did you have previously? Were you running Windows XP on your old setup and this is just an upgrade? or is this a fresh install? It may be that the old motherboard drivers don't match up to your new motherboard, so perform a Windows Repair using the WinXP CD (backup first of course).

After that, proceed to installing the latest drivers available for your motherboard chipset drivers etc from the manufacturer's website or from the CD.

Do not attempt to change anything you don't know what its for. You may cause more harm than good.

If the above didn't solve your problem, then other troubleshooting methods may be needed, such as:

-Reset CMOS/BIOS: If your mobo has a reset jumper, activate it, then put it back to normal, or if it doesn't, look for a round button battery and remove it for 15 seconds then replace it.

-Going back to minimum setup -> CPU/Motherboard, 1 HDD, 1 stick of RAM, Audio, Video, Power. While you have your PC opened up, it may be a good time to observe if there's any signs of damage eg. popped/leaking capacitors, burns or irregular marks, smell etc.

-Download and use Memtest bootup disk and test 1 stick of your RAM at a time. Let it do 7 passes (it will take a while) and see if anything Fails/errored. Do the same for any other sticks of RAM. Lastly if you're running dual channel, perform the test again with both sticks on, to determine compatibility. If it does fail the test, then you have some bad RAM or incompatible RAM.

-SAFE MODE. Boot up to this, and tell me if its stable or not.

After each one, boot up and see if its stable. If it is, then you just have to build up from there and see what is causing the problem. If it doesn't, then move on to the next step.

Your voltage readings look fine, except for the +5V line? Download Everest Home or Speedfan or go into BIOS Hardware monitor and confirm these readings. Check temperatures too.
